Elmar Pruesse, as per http://download.lenovo.com/express/ddfm.html an update is available for your BIOS (1.38). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything?
If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1239358 Title: [Lenovo x220] display port stopped working after move to 13.04 Status in “linux” package in Ubuntu: Incomplete Bug description: I get a blank (turned off) display on an Eizo monitor connected via DisplayPort to a Lenovo x220. The display works on 12.10 and does work while booting. As soon as X starts, the display is gone. Xrandr does show it and it can be configured. The screenshot tool shows entire area correctly. But nothing appears on the screen. Reconnecting the cable does the usual flicker, as does power cycling the monitor. The display stays blank. On 12.10 something similar occurred intermittently. After closing the notebook lid, the monitor had to be powercycled (re-plugging the cable did not help).
